God is the source of all truth (Isaiah 46:9-10; John 17:17). Gods authority In the New Testament dispensation, and therefore in the time in which we are living, is revealed and exercised through Jesus Christ (Hebrews 1: 1-2; Matthew 28:18; Ephesians 1: 17-23; Matthew 17:5; John 12:48). We find this authority plainly set forth by the disciples who spoke and wrote the Bible under the influence of the Holy Spirit (John 16: 13; 14:20: 2 Timothy 3: 16-17).Therefore, the ones who are following the only safe course in religion today are the ones following the Bible. The others are following courses of men, which will lead to destruction and damnation (Matthew 15: 7-14).
